摘要
A novel chemosensor for fluoride anion has been developed. This sensor, constructed by merging six phenolyl units into a hexaazatriphenylene (HAT) core, could recognize F- visually and spectroscopically with high selectivity over other anions, which was demonstrated by naked-eye experiment and UV-vis absorption spectroscopy study.
